If you need to scan virus on Hopedot VOS system, you can simply do it by using the system anti-virus software to scan the whole Hopedot VOS folder, so you don't need to install anti-virus program in Hopedot VOS virtual system, just install it in host system.

One advantage of Hopedot VOS is that even if Hopedot VOS gets a virus, it will not affect your host computer because Hopedot VOS is independent of system drive, so it will not affect the host computer.

We also want to clarify that Hopedot VOS as a virtual system, it does not support installing and running anti-virus program on it very well. So we suggest you to use a host computer which has an anti-virus program to run Hopedot VOS, or just install some small protection programs on it such as ClamWinPortable、a-squared Emergency USB Stick to protect VOS.
